NUT-LOCK.

Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed June 6, 1905. Renewed August 15, 1906. Serial No. 330,739.

To all whmn it may concern:

Be it known that I, JOHN H. BALDWIN, a citizen. of the United States, residing at Beaumont, in the county of J etlerson and State of Texas, have invented new and useful Improvements in Nut-Locks, of which the following is a specification.

My invention relates to nut-locks; and its primary object is to provide a novel and highly useful device of this character which, although especially adapted for securing against accidental displacement a nut upon a bolt used in connection with rail-joints, is also equally well adapted to look a nut upon a bolt used in connection with any other construction.

The invention consists in the construction, combination, and arrangement of parts more fully hereinafter described, claimed, and ill: strated in the accompanying drawings, which disclose the preferred form of my invention, and in which Figure 1 is a detail perspective View of my nut-lock; and Fig. 2 is a View in side elevaitiorli, illustrating the application of the nutoc i.

Referrin to the drawings by referencenumerals, the nut-lock comprises a plate 6, struck up from any suitable material and provided with a central orifice 7, by means of which said plate may be mounted upon the bolt between the nut and the portion agairst which it is secured. The plate 6 is provided with two acute-annular incisions 7 providing said plate with a nut-engaging member 8, which when the plate is in applied position upon the bolt is adapted to be bent to bring the acute-angular edges thereof into engagement with two sides of the nut to secure the nut in applied position against accidental displacement.

As disclosed in Figs. 1 and 2, the invention resides in providing the plate 6 with prongs 11. These prorgs are formed integral with the plate 6 and are adapted to be bent into horizontal position, as disclosed in the view shown. This provision of the plate 6 with the prongs 11 adapts the same for application to constructions other than that of railjointsas, for instance, where the bolt is used in connection with wooden constructions the prongs 11 are adapted to be driven therein, and thus hold the plate in a position upon the bolt agaizist turning.

After the plate has been inserted upon the bolt between the nut and the member through which the bolt projects a tool is inserted behind the curved corner of the nutengaging member 8 and the same is bent so as to bring its acute-angular edges into engagement with two sides of the nut, as illustrated in 2 of the drawings.

Having thus fully described the invention, what is claimed as rew is- In a nut-lock, the combination of a rectangular plate slitted to provide an acute-angular member in its upper portion, and cut away in its lower portion to provide two pointed members, said pointed members adapted to be bent at right angles to the plate and serve as securing means thereto.

In testimony whereof I afliX my signature in presence of two witnesses.

JOHN H. BALDWIN.
